Beautifully/thrillingly layered songs

[Chibi-Chan]

Since a few years I'm missing songs in Ayu's discography that are beautiful/thrillingly layered. So could you recommend me some songs? For example I'm searching for songs which are as great layered as HANABI or Fall Out Boys "Fourth of July" if you need a recent example (sadly there isn't any recent Ayu song that comes to my mind that would be beautifully layered).
